I think you may be right as the A6h is not equipped with adaptive air suspension. The guy at audizine claimed that the standard Audi drive select mode also 'tightens' the damping of the absorbers/suspension in dynamic modes while the AAS allows for more dynamic changes to speed including lowering and raising the height of the car. Don't know which is correct but one thing's sure, use comfort mode for longer distance drives. The car will be very much at home in auto mode settings in normal city drives

Dynamic -for that clear city roads on weekends or first part of that famous long twisty stretches of the Karak - East Coast highway

Individual - my default setting now for city drives. I find The steering to be too light on auto thus I adjusted for the steering to be in dynamic while engine/gearbox to be in auto. Tighter steering control now, still light and devoid of road feel but much better than auto mode exclusively.
